Hi! I've had this aircraft (757 III P3Dv4) for a bit now and have used it several times without any issues. Today I was unable to open the 1st and 2nd entry doors with the Animations Control Panel. Everything else seems to work fine, except the occasional cargo door that won't open either. I finally followed the reinstallation instructions (exactly). That worked. Once. Then it did the same thing. I had to use Shift+E to open the main entry door. I'm at a loss as to why this is not working...and all of a sudden no less. Any ideas?
